Abstract (en)
[origin: EP2019229A2] An automotive gear box has a drive shaft (1), two input shafts (5, 6) and a double clutch (2) that transmits torque from the drive shaft (1) as selected into the first or second input shafts (5, 6). The gearbox further has a number of cog sets (7, 9; 8, 10; 8, 12; 16, 17; 16, 18, etc) that transmit torque from the first or second input shafts to an intermediate shaft (11, 13). A first set of cogs (8, 10) transmits torque from the first input shaft (6) and a second set of cogs (7, 9) that transmit torque from the second input shaft (5), have the same gear ratio.
